Interpretive Summary: The caterpillars of leaf-roller moths attack a variety of crops, ornamental plants, and forest trees, inflicting billions of dollars of damage annually. This paper examines an array of leaf-roller moths that occurs in Central and South America, with the purpose of describing several species as new to science. It provides descriptions, diagnoses, and illustrations of the genitalia which will allow them to be identified. This work will benefit scientists involved in biodiversity studies in the New World tropics and APHIS-PPQ personnel and other action agencies whose goal is to prevent the entry of invasive species at U.S. borders.

Technical Abstract:
The tortricid tribe Eulini occurs almost exclusively in the Western Hemisphere with its greatest species richness in the tropical regions. Life history information indicates polyphagous habitats similar to that of other Tortricinae. In the present work we describe and illustrate 7 new species of Neotropical euliines: Galomecalpa meridana (Venezuela); Quasieulia jaliscana (Mexico); Hynhamia ochroleuca (Costa Rica); Gauruncus venezolanus (Venezuela); Transtillaspis tucumana (Argentina), T. cinifera (Venezuela), and T. anxia (Colombia). One new combination is proposed: Galomecalpa defricata (Meyrick).
